I found this Fish Pond stepping stone design in a Stained Glass newspaper. I had never made a large stepping stone before so decided this would make a great project. Seven stones that can be arranged in various patterns.
I found the blue glass at Phoenix Stained Glass in Portland and the rest at Acadian Stained Glass in Saint John (now out of business).
This was an educational experience and a very enjoyable one. Greatest challenge; getting the right consistency of the concrete.
